The hand-held power tool may be an electric motor driven tool or pneumatic motor-driven tool. The hand-held power tool may also be a drill, a screwdriver, a wrench, a circular saw, a reciprocating saw or an electric hammer. In the following illustrated embodiment, an electric motor-driven impact wrench is taken as an example for the detailed description.
- Referring to
FIGS. 1 and 2 , a hand-heldpower tool 100 includes ahousing 10, amotor 20 and atransmission mechanism 30 received in thehousing 10, apower source 40 for providing power to the motor, aswitch 50 received in the housing for controlling themotor 20, atrigger 60 for activating or cutting off theswitch 50, anoutput shaft 70, anilluminating assembly 80, and anexecution element 90. Thetransmission mechanism 30 transmits the rotary power of themotor 20 to theoutput shaft 70. Theoutput shaft 70 drives theexecution element 90. Theilluminating assembly 80 is used to illuminate theexecution element 90 or a work-piece, and it is convenient for the users to clearly see the position of theexecution element 90. - The
housing 10 includes afirst housing portion 11 for receiving themotor 20, asecond housing portion 12 for receiving thetransmission mechanism 30, and athird housing portion 13 for receiving theswitch 50. Thefirst housing portion 11 defines a first longitudinal axis W. Thesecond housing portion 12 is fixed to thefirst housing portion 11. It should be noted that, thefirst housing portion 11 and thesecond housing portion 12 may be integrally made. Preferably, thesecond housing portion 12 and thesecond housing portion 12 are made of a different material, for example, thefirst housing portion 11 is made of plastic and the second housing portion is made of metal material. In the illustrated example, thefirst housing portion 11 is made with nylon and thesecond housing portion 12 is made of aluminum alloy. Thefirst housing portion 11 includes two half shell assembled to each other. Thesecond housing portion 12 is made by die-casting or other manufacturing process. Thefirst housing portion 11 and thesecond housing portion 12 are mutually fixed by a fixing element. Thethird housing portion 13 forms a gripping portion for facilitating a user to hold the hand-heldpower tool 100. Of course, it should be noted that, a gripping portion may also be formed on thefirst housing portion 11 or thesecond housing portion 12 for a user to hold. One end of thethird housing portion 13 is connected to thefirst housing portion 11 andsecond housing portion 12. Another end of thethird housing portion 13 may be formed or fixed with an engaging structure (not labeled) for mounting thepower source 40. - The
motor 20 may be an electric motor or pneumatic motor. In the illustrated embodiment, themotor 20 is an electric motor. - The
transmission mechanism 30 transmits the rotary motion of the motor to theoutput shaft 70. Thetransmission mechanism 30 is a well-known structure in an impact wrench, such as the transmission mechanism described in the U.S. Pat. No. 6,733,414B2. - The
power source 40 may be a direct current power supply, a battery pack or an AC power source. In the illustrated embodiment, thepower source 40 is a battery pack for providing direct current power. - The
switch 50 may be used for controlling themotor 20 to start and stop. If necessary, theswitch 50 may control the rotating direction and speed of themotor 20. Thetrigger 60 is installed in thethird housing portion 13. The user is capable of adjusting the rotating speed of themotor 20 by adjusting the amount of pressing upon thetrigger 60. Thetrigger 60 may further include a reversing knob for adjusting the rotating direction of themotor 20. - The
execution element 90 is mounted on theoutput shaft 70 by a clamping assembly (not labeled). The illuminatingassembly 80 helps the user to clearly see the position of theexecution element 90 or of the work-piece machined by theexecution element 90. - Referring to
FIGS. 3-13 , in the following section, theillumination assembly 80 will be illustrated in detail. - The illuminating
assembly 80 is mounted on thehousing 10 and includes a plurality oflighting elements 81, acircuit board 82 electrically connected with thelighting element 81, amain body 83 covering thelighting element 81 and thecircuit board 82, awire 84, awire guide 85, and fixingmembers 86. Thecircuit board 82 is capable of supporting thelighting elements 81. Themain body 83 permits the light illuminating from thelighting element 81 to pass there-through. Thelighting element 81 and thecircuit board 82 are fixed to thesecond housing portion 12 by themain body 83 cooperative with the fixingmembers 86. The plurality oflighting elements 81 are evenly distributed on thehousing 10 around the first longitudinal axis W, thus light can be illuminated from a plurality of different angles and preventing shadow from being formed on a corresponding region adjacent to theexecution element 90. Therefore,such lighting elements 81 can also be referred to as shadow-less lighting elements. - In one embodiment, the
lighting elements 81 are three Pin type LEDs evenly distributed around the first longitudinal axis. Themain body 83 includes afirst cover 830 having a substantial portion that is sleeved on thehousing 10 and asecond cover 831 for light illuminated from thelighting elements 81 to pass there-through. The fixingmembers 86 are two screws. Thesecond cover 831 forms three receivingportions 833 for respectively receivinglighting elements 81 and defines two throughholes 834. Each fixingmembers 86 is capable of passing through one of the throughholes 834. The receivingportions 833 are transparent and permit light illuminated from thelighting elements 81 to pass there-through. Thefirst cover 830 andsecond cover 831 may be both or only one made of transparent material. Thefirst cover 830 andsecond cover 831 may also be integrally formed. In another embodiment, as shown inFIG. 12 , thelighting elements 81 may be three patch type LEDs evenly distributed around the first longitudinal axis, thereby further decreasing occupied space of thelighting element 81 and thecircuit board 82. It should be noted that, light emitting from thelighting elements 81 may not pass through themain body 83, thus thelighting element 81 and acircuit board 82 are partially received in themain body 83, and a predetermined portion of thelighting elements 82 where light is emitted is outside themain body 83. - When the
first cover 830 and thesecond cover 831 are separate parts, thesecond housing portion 12 forms a mountingportion 120 for receiving the fixingmembers 86. The mountingportion 120 defines a second longitudinal axis X parallel to the first longitudinal axis W. The fixingmembers 86 pass through thesecond cover 831 to fix thefirst cover 830, thesecond cover 831, thelighting element 81 and thecircuit board 82 to thesecond housing portion 12. Therefore, thelighting elements 81 are compactly fixed to thesecond housing portion 12. - Each fixing
member 86 defines a third longitudinal axis Y. The second longitudinal axis X and third longitudinal axis are positioned in the same axis. Thefirst cover 830 forms a plurality ofstop portions 835 arranged along a radial direction of the first longitudinal axis W and extending towards the direction of the first longitudinal axis W, and defines a plurality ofgrooves 836 arranged along a radial direction of the first longitudinal axis W and extending towards a direction away from the direction of the first longitudinal axis W. Thefirst cover 830 further includes afirst end 837 distal from thesecond housing portion 12 and asecond end 838 mounted on thesecond housing portion 12. Thestop portion 835 is used for preventing thesecond cover 831 from moving along the first longitudinal axis. Thefirst end 837 forms anend surface 839. The second cover forms a plurality of restrictingportions 8310, a plurality ofprotrusions 8311, and anouter surface 8312 positioned adjacent to theend surface 839. The restrictingportions 8310 are arranged along a radial direction of the first longitudinal axis W, and extend away from the direction of the first longitudinal axis W, and are prevented from moving along the first longitudinal axis W by thestop portions 835. Theprotrusions 8311 are arranged along a radial direction of the first longitudinal axis W, and extend away from the direction of the first longitudinal axis W. Theprotrusions 8311 are capable of extending through thegrooves 836. In order to cover thecircuit board 82 and get a beautiful appearance, theoutput shaft 70 should extend through thefirst cover 830 and thesecond cover 831, thesecond cover 831 is used for covering the gap betweenfirst cover 830 andsecond housing portion 12. - When the hand-held
power tool 100 is an impact wrench, relatively high vibrations are generally caused in the operating process. In order to prevent these vibrations from damaging thelighting elements 81 or thecircuit board 82, the illuminatingassembly 80 further includes a shock-absorbingelement 87 positioned between thesecond housing portion 12 and thecircuit board 83. It should be noted that the shock-absorbingelement 87 may also be positioned between themain body 83 and thecircuit board 82. In one embodiment, the shock-absorbingelement 87 is an elastic O-ring positioned on thecircuit board 82 and thesecond housing portion 12. The shock-absorbingelement 87 may also be a plurality of rubber columns arranged between thecircuit board 82 and themain body 83. - In order to make the hand-held
power tool 100 more compact, thecircuit board 82 at the front end is electrically connected to amain circuit board 51 of the hand-heldpower tool 100 by thewire 84, so that thelighting element 81 is provided power from a battery pack of the hand-heldpower tool 100. It should be noted that thelighting element 81 can also get power from an independent power supply, such as a button battery mounted in thehousing 11. Furthermore, in order to prevent oil in thetransmission mechanism 30 from contaminating thewire 84, thethird housing portion 13 defines a fourth longitudinal axis Z substantially perpendicular to the first longitudinal axis W. Thewire 84 includes a first end electrically connected to thecircuit board 82, and a second end opposite to the first end electrically connected to themain circuit board 51. Thewire guide 85 includes afirst guide portion 850 and asecond guide portion 851. Thesecond guide portion 851 is positioned between thefirst housing portion 11 and thesecond housing portion 12. Thewire 84 passes thefirst guide portion 850 to extend through thesecond housing portion 12 and is guided by thesecond guide portion 851. - Preferably, the
first guide portion 850 is positioned in thefirst cover 830 or in thesecond housing portion 12. Thesecond guide section 851 is positioned in thefirst housing portion 11 or in thesecond housing portion 12. Thesecond housing portion 12 may be partially received in the first housing portion. Thefirst guide portion 850 is located in or above a plane that the first longitudinal axis W is positioned in and the plane is perpendicular to the fourth longitudinal axis Z. Thesecond guide portion 851 extends along a circumferential direction of the first longitudinal axis W. Thefirst guide portion 850 may be integrally formed with thefirst cover 830 or thesecond housing portion 12. Thefirst guide portion 850 may also be a separate element fixed to thefirst cover 830 or thesecond housing portion 12. Thewire guide 85 effectively avoids thewire 84 being contaminated by oil in thetransmission mechanism 30. In addition, thefirst guide portion 850 is located in or above the plane including the first longitudinal axis and perpendicular to the fourth longitudinal axis Z, thus the whole structure of the hand-heldpower tool 100 becomes more compact. If thefirst guide portion 850 is positioned below the plane, the whole structure of the hand-heldpower tool 100 may become larger, in particular, a finger holding area between thetrigger 60 and thesecond housing portion 12 becomes larger, thus causing it to be difficult to hold in the finger platform region. - If the
second housing portion 12 is made of metallic material and thepower tool 100 is an impact wrench, after a relatively long time operation, a great amount of heat may be generated on thesecond housing portion 12. Therefore, thepower tool 100 further includes aheat insulating member 88 made of high-temperature-resistant material, and theheat insulating member 88 is positioned between thesecond housing portion 12 and thewire 84 for isolating heat and effectively protecting the wire. Thus, thewire 84 is effectively prevented from overheating and failure. In another embodiment, an insulating layer of thewire 84 is made of a high-temperature material. Preferably, theheat insulating member 88 is made of heat shrinkable sleeve or yellow wax tubes. - The
lighting elements 81 may also be used for indicating insufficiency of remaining capacity of the battery pack. At least one lighting element is used for indicating whether the battery pack has a sufficient power source. When the battery pack has an insufficient power source, at least one of the lighting elements produces an alarm signal that a human can perceive. Referring toFIGS. 14 and 15 , an indicatingcircuit 89 for showing insufficiency of remaining capacity of the battery pack includes atrigger control module 890, apower supply module 891, lightingelement control module 892, voltagesignal detection module 893 and lightingelement indicating module 894. A user switches thetrigger control module 890 so that thepower supply module 891 can provide energy to the lightingelement control module 892. A voltage signal detected by the voltagesignal detection module 893 is compared to a preset voltage in the battery pack, when the detected voltage value is greater than the preset voltage value, thelighting elements 81 display white light, when the detected voltage value is lower than the preset voltage value, thelighting element 81 display red light. It should be noted that, thelighting element 81 can emit other human perceptible signal, such asmake lighting element 81 flash, or a buzzer is arranged additionally, when the insufficient power source is detected, the buzzer alarms. - As shown in
FIGS. 16-20 , a second embodiment of the present disclosure provides a hand-heldpower tool 100′, an electric motor-driven impact wrench is still taken as an example for the following detailed description. - The hand-held
power tool 100′ in the second embodiment is similar to the hand-heldpower tool 100 in the first embodiment. The hand-heldpower tool 100′ also includes a first housing portion including 11′, asecond housing portion 12′, asecond housing portion 13′ and an illuminatingassembly 80′. However, each of the first housing portion including 11′, thesecond housing portion 12′, and thesecond housing portion 13′ includes two half housing portions. - Furthermore, the illuminating
assembly 80 is positioned on thesecond housing portion 12′ and includes alighting element 81′, acircuit board 82′, amain body 83′, awire 84′, awire guide 85′ and fixingmembers 86′. Thelighting element 81′ is mounted on thecircuit board 82′. Themain body 83′ permits the light illuminated by thelighting element 81 to pass there-through. Thelighting element 81 and thecircuit board 82 are covered by themain body 83′. Thecircuit board 82′ is electrically connected to amain circuit board 51′ by thewire 84′. The wire guide 85′ includes afirst guide portion 850′ positioned on thesecond housing portion 850′ andsecond guide portion 851′ positioned on the second housing portion. Themain body 83′ includes afirst cover 830′ and asecond cover 831′. Thefirst cover 830′ and thesecond cover 831′ are fixed to thesecond housing portion 12′ by the fixingmember 86′. - When the text of the connection relations referred to in terms, such as “connected”, “fixed” and “received” and the like, it can be understood as one of the elements is directly connected to, fixed to or received in another element. It can also be understood as one of the elements is indirectly connected to, fixed to or received in another element by a third element or more elements.
- The above illustrates and describes basic principles, main features and advantages of the present disclosure. Those skilled in the art should appreciate that the above embodiments do not limit the present disclosure in any form. Rather, technical solutions obtained in a way of equivalent substitution or equivalent variations are all intended to fall within the scope of the claims set forth hereinafter.
